I have a close friend, who I thought was a long time recovered addict, that has been caught lying on many occasions. Recently, he said he needed a B12 shot for his lack of energy. He says he went in to see his doctor and "just got one because I asked." Can anyone walk in off the street to see the doctor and say you need a B12 shot and just get it? No questions asked? I'm hoping that maybe he's beginning to see his problem and maybe didn't lie about this. I want to give the benefit of doubt but I still don't know if he's being honest.
